Altocumulus clouds act as a visual cue for a changing weather pattern. These are the types of clouds that appear ahead of a strong cold front and are a common sight. They indicate the presence of ...

The main part of this cloud is made of an altocumulus cloud. These midlevel clouds form between 7,000 to 23,000 feet and develop in a similar way as cumulus clouds or thunderstorms.

Altocumulus clouds are usually found in groups, clumped together rather than floating along as puffy blobs like cumulus clouds that would form closer to the ground. If you’ve ever seen a ...

According to the National Weather Service (NWS), these clouds are specifically "neat looking altocumulus with virga." But what exactly does that mean?

News Weathercatch: When a cloud mesmerized the Inland Northwest Thu., Feb. 16, 2023 National Weather Service forecaster Jon Fox captured an unusual altocumulus cloud formation in 2015 to the east ...

These clouds are called altocumulus floccus clouds. The tentacle-looking streaks are ice crystals falling from the cloud but evaporate before they reach the ground, known as virga.

According to WRAL meteorologist Aimee Wilmoth, these clouds that resemble jellyfish are patchy altocumulus clouds with virga (rain that evaporates before it reaches the ground) at the bottom of ...

Altocumulus clouds are composed of water droplets that, in cooler environments, become super cooled. That is, they remain in a liquid state at temperatures below the freezing point of water.

A rainbow cloud can occur because of something called cloud iridescence. It usually happens in altocumulus, cirrocumulus, lenticular and cirrus clouds. Iridescent clouds happen because of ...

The formation is called a fallstreak hole, or a hole punch cloud. It's a circular or elliptical gap that can appear in a deck of cirrocumulus or altocumulus clouds.

How do fallstreak holes form in the sky? The unique cloud formation occurs when airplanes pass through mid-level altocumulus clouds containing supercooled water droplets.
